# Pi Day

An appropriate date for math fun.

The date March 14 is often written as 3/14, corresponding to the first three digits of the number π (3.14159265358979...), so has grown into national celebration of the constant. The University of Arizona generally puts on events as part of these festivities, some involving the Arizona Mathematics Road Show Bus.## When
